Looming loss of crucial satellite system is latest blow to U.S. hurricane forecasting
Hurricane forecasters are at risk of losing a crucial tool because of military concerns surrounding the cybersecurity of a long-shared satellite system — the latest potential cut to federal weather science programs by the Trump administration. After criticism and questions from a slew of forecasting experts, the Department of Defense on Monday announced that it is postponing the cutoff of the critical satellite imaging for at least a month. Unless that deadline is extended or the military concerns resolved, forecasters would have a less precise picture of storms overnight, potentially leading to delays of six hours or more in forecasts, or even delayed watches and warnings to people in the path of storms, said James Franklin, a former head of the National Hurricane Center. 'There is no substitute for this imagery, and it will affect certain kinds of forecasts from the National Hurricane Center,' said Franklin, who retired from the NHC in 2017. 'This is a big deal.' After a high-level NASA employee intervened, the department announced Monday it was delaying the decommission until July 31, just before the August and September peak of what is expected to be another above-average hurricane season. That may only be a temporary reprieve. The looming loss of the high-tech microwave imaging is only the latest in a series of announced cuts by the Trump administration to hurricane research, including the loss of uncrewed vessels called Saildrones that capture data and Internet-popular video from the eye of the storm. A detailed budget request released Monday also calls for ending the majority of research conducted by the National Oceanic and Atmospheric Administration — including the Miami-based Atlantic Oceanographic and Meteorological Laboratory, home of the Hurricane Research Division. READ MORE: With hurricane season ahead, Trump cuts leave Florida weather offices understaffed Last week, in the latest controversial proposed cut, the Department of Defense announced it would abruptly stop sharing data from its Defense Meteorological Satellite Program, three weather satellites that are co-operated with NOAA due to 'a significant cybersecurity risk.' While Franklin said he has no explanation for what might suddenly concern the military on a system in use for decades, he and other meteorologists would like to see the service maintained through at least the end of hurricane season. 'How serious a cybersecurity threat can it be, then, if you can extend it a month? If you can extend it a month, can you extend it through the peak of hurricane season?' he asked. NOAA did not immediately respond to a request for comment from the Herald, but an agency spokesperson downplayed concerns, telling Michael Lowry of Local10 that the missing satellite is 'a single dataset in a robust suite of hurricane forecasting and modeling tools in the NWS portfolio.' 'NOAA's data sources are fully capable of providing a complete suite of cutting-edge data and models that ensure the gold-standard weather forecasting the American people deserve,' the agency said. 'Sunrise surprise' Meteorologists say these satellites are irreplaceable. No other source of data or tool available gives the same look into the guts of a storm through the clouds at night. The Special Sensor Microwave Imager Sounder, or SSMIS, allows forecasters to keep an eye on major changes to the rain bands surrounding the core of a storm during a dark and cloudy evening. That, Franklin said, gives forecasters clues as to whether a storm is about to get much stronger, much faster, a process known as rapid intensification. Before that system — or without it — forecasters would get a 'sunrise surprise,' he said. They would wake up to a much stronger or different storm than they saw the previous evening — and eight hours closer to making landfall. 'When you lose that, when these SSMIS data go away, and a forecaster is looking for clues that a storm is about to undergo this rapid strengthening process, it may be hours of delay before those clues are apparent from other types of data,' he said. 'You might have known that six, ten hours earlier if you'd had one of these microwave passes.' The satellite data also gives forecasters a chance to watch out for eyewall replacement cycles. A strengthening storm will often form a new eye that envelops or overtakes the original one. In the middle of that process, a storm gets weaker but also grows wider, meaning the impacts spread along a much bigger area. When a storm goes through an eyewall cycle right next to land, like Hurricane Katrina did in 2005, it can have a significant impact on who gets hit and how hard. Former hurricane hunter Andy Hazelton said the satellite also helped scientists about to fly into a storm see what they were up against and prepare for their mission. 'The microwave satellite is a key piece to look under the hood of a storm. It tells us what to expect,' said Hazelton, now an associate scientist with the University of Miami. While hurricane hunter planes are 'the best available tool' for peering inside a storm and seeing changes like these, planes aren't sent out for every storm. So the microwave passes remain the best option for far-off storms, weaker storms or watching a storm in between plane flights, Franklin said. And the loss of that data could be critical, especially for plotting the center of far-flung developing systems. 'Without the microwave imagery, I think some of these initial position estimates could easily be off by 50 or 60 miles or more in some cases,' he said. 'The less well you know the initial state, the more the errors grow in time.' Few possible replacements In its statement, NOAA pointed to another satellite tool that also offers forecasters a view of storms — the Advanced Technology Microwave Sounder or ATMS. But hurricane scientists say it lacks the finer details of the military satellite getting taken offline. 'It's like the graphics of a video game from the late '80s compared to the 2010s,' said Hazelton. 'The resolution isn't there.' The satellites are not young, fresh tech. The first one in the program was launched in 1964, and NOAA didn't assume shared responsibility over the technology until 1994. Franklin said he understands that at least one of the three is set to be phased out in September of next year. But there are no immediate plans for a replacement. A new Department of Defense satellite with similar capabilities is set to launch in October, but Franklin said it isn't clear if that data will be available for forecasters. 'The decision to just turn off the data processing when there's still usable life left is somewhat inexplicable,' he said. 'This is truly a self-inflicted wound.' 'Hit after hit' The loss of the crucial satellite comes weeks after NOAA ended its contract with Saildrone, a private company that provided several uncrewed drones that observed hurricanes from the air and sea and fed the data back to scientists. 'Unfortunately, due to the timelines associated with contracting, shipping, and transit, Saildrone is unable to support the Atlantic Hurricane mission this season,' the company said in a statement. 'Our long-standing partnership of innovative collaboration with NOAA continues across many other mission opportunities.' Hazelton, the hurricane researcher, said the information provided by Saildrone was 'more experimental' than the satellite, but still helped inform and improve storm models. 'The more data, the better,' he said. 'It kind of feels like one hit after another with losing these pieces of data.' On Monday, NOAA released a more detailed budget request for the coming year for Congress to approve. While it doesn't differ from the broad strokes of the budget released earlier this year, it offers even more detail on what cuts the agency could see under the new presidential administration. The budget calls for cutting all NOAA research at climate labs and cooperative institutes across the country, including the Miami-based AOML lab and its academic partnership with the University of Miami. Hazelton calls this a massive blow to what has, for decades, been a bipartisan mission: improving hurricane forecasting. The administration said that crucial weather services would be re-organized under the National Weather Service, but it did not provide details. 'The proposal would basically get rid of all NOAA research,' he said. 'Pretty much all of our research and development and modeling would be hit by this, even if on paper they're moved to the National Weather Service.'

Federal Forecasters Lose Access to Critical Tool as Hurricane Season Begins
As Atlantic hurricane season surges to life, federal forecasters must say goodbye to one of their most valuable tools—Saildrones. These uncrewed ships sail into the hearts of tropical storms to collect real-time data that scientists use to predict their strength and path. For the past four years, the National Oceanic and Atmospheric Administration (NOAA) has deployed Saildrones to improve the accuracy of its hurricane forecasts and warnings. The small drone ships have played an especially important role in predicting rapid storm intensification, which drastically increases the extent of a hurricane's impact. This year, however, the California-based company behind Saildrone was 'unable to bid' on a NOAA contract, agency spokesperson Keeley Belva told Gizmodo in an email. Belva did not say why Saildrone was unable to bid. According to a NOAA employee who spoke with CNN on condition of anonymity, the agency sent out its request for contract proposals too late, preventing Saildrone from bidding and from pre-deploying its fleet to multiple launching ports in the Atlantic and Gulf Coast ahead of hurricane season. 'NOAA continues to explore the use of other uncrewed systems in meeting the agency's data needs within hard-to-access regions of tropical cyclones during the 2025 season,' Belva told Gizmodo. 'The agency is preparing for the use of uncrewed surface vehicle deployments with industry partners for the 2026 season.' The news adds to growing concerns about the agency's readiness for hurricane season, which officially began on June 1. Since President Donald Trump took office, NOAA has faced sweeping staff cuts, grant freezes, and travel and training restrictions, according to the Associated Press. The agency's National Weather Service (NWS) office alone has lost over 10% of its staff since January, CBS News reported. Now, the Trump administration's 2026 budget proposal threatens to reduce NOAA's budget by $1.6 billion. Despite the upheaval—and forecasts for above-normal Atlantic hurricane season activity—NOAA representatives say they are prepared. Losing Saildrone, however, marks another significant blow to its forecasting abilities. According to NOAA, the remotely operated ships are equipped with a suite of instruments that allows them to take multiple concurrent measurements of the environment. They gather data on wind speed, wave height, temperature, pressure, salinity, and, perhaps most importantly, the transfer of heat and moisture between the ocean and the air directly above it. This dynamic plays a critical role in storm intensification. By measuring it, scientists can predict how a hurricane will develop over time. Saildrones transmit data to forecasters in real time, helping them refine their forecasts and public messaging. This year, NOAA had plans to further improve forecast accuracy by incorporating Saildrones observations directly into forecast models, NOAA oceanographer Gregory Foltz told CNN. The ships also capture footage from inside hurricanes, producing harrowing live videos of these intense storms. Such powerful imagery may influence peoples' decisions to evacuate by showing how severe storm conditions are, Foltz said. Without Saildrones, NOAA will have to lean on its aerial storm-tracking tools. These include weather balloons and new lightweight drones launched from the bellies of the agency's two WP-3 hurricane hunter aircraft. The drones—specifically the Black Swift SØ—are designed for rapid atmospheric profiling, capturing data on air temperature, wind speed and direction, dewpoint, and atmospheric pressure. The agency will also deploy StreamSonades, which are tiny biodegradable probes that NOAA can drop from a hurricane hunter aircraft to collect atmospheric measurements as they fall through the storm. While valuable, these aerial tools can't match Saildrone's ability to provide live storm footage or reliably measure wind and sea surface temperatures over long periods of time. As a scaled-back NOAA puts on a brave face for hurricane season, sidelining Saildrones will strain its resources even further.
